Hello all,
            The company I work for has multiple physical sites around the world, each site has thier own independant 2003 server active directory domain setup. All running off seperate DNS (some UNIX bind, some microsoft dns). We also have a top level AD domain that is utilised for exchange mail. We were looking @ replacing all these seperate domains with a single domain running off MS dns, but this has been deemed unworkable due to the need to have a PDC emulator @ each site to allow for older MS systems & unix to authenticate to regardless of the status of the wan link. Therefor the plan is to create a tree structure joining all the different domains together allowing for us to share resources & have a single sign on (we currently have multiple password for different services) etc etc.  (top level AD only utilised for exchange mail)  (another site AD used for full services)  (another site AD used for full services)  (another site AD used for full services)
etc etc

I wanted to check to ensure
A) this is possible
B) whether this arcitecture will allow single sign on
C) possible methods of deployment considering these domains are already present
D) if there are any major issues with this apporach

Many thanks....
